Magnetic thin films - Near-field optical microscopy
Prof. Dr. Paul Fumagalli
Building Department of Physics
Our activities lie in the field of experimental solid-state physics, with the following core areas:
Magnetic thin films
We examine growth and magnetic properties of films that are just a few atomic layers thick. A range of different methods is used for analysis, including electron diffraction and rotation of light polarization by polar Kerr effect.
Near-field optical microscopy
In this method, the electromagnetic field emitted by the tapered end of a glass fiber is used as a probe. We have been developing such microscopes for years,using them to examine magnetic and optical properties on a nanometer scale. The method is also ideally suited to examining biological systems.
